That's the thing though... nobody in forums claimed to have won a prize(other than the instant prize). You would think that at a minimum, one person would come forward and say they won something. I had almost 1600 for travel and well over 600 for Tablets, 600 for gift cards... but didn't win anything. It sure sounds fishy to me.
I think it's rigged because they would have posted the list of winners like any other site does. I didn't win anything and have wondered who won too. Seems fishy that we don't have at least one person indicating that they've won a prize.
